In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypoethical particle, known ...

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — ...

Physicists working on the LHCb experiment at CERN’s Large Hadron Collider have discovered a new subatomic particle called the Ξcc⁺, a heavy cousin of the proton built from two charm quarks and one ...

Researchers from the University of Rochester have helped measure the elusive top quark with unparalleled precision, and the surprising results affect everything from the Higgs boson, nicknamed the ...

The Large Hadron Collider (LHC) is also a big hadron discoverer. The atom smasher near Geneva, Switzerland, is most famous for demonstrating the existence of the Higgs boson in 2012, a discovery that ...

Protons may have more "charm" than we thought, new research suggests. A proton is one of the subatomic particles that make up the nucleus of an atom. As small as protons are, they are composed of even ...

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons ...
